It's a real thing, I think it's incredible, but it's real.
In the early nineties of the last century, there was a year when the Chinese New Year was coming, and the unit paid benefits to employees. I sent a very general silver carp, because the unit is far away from home, it is snowing, and I can't go home for a while, and there is no refrigerator, so I am afraid that the fish will be broken and bury the fish in the snow to prevent it from freezing.
When I came home from vacation a few days later, I took the fish home. At the time, I didn't think much of it, just took a basin and filled it with cold water, and put the fish that had been frozen into ice cubes. After a while, I was very surprised, the mouth of the fish seemed to be moving, and if I looked closely, it was indeed moving, and the breathing became more and more obvious, although I was sideways, but the breathing was already very obvious, and then I swam sideways, and then I swam like a normal fish.
However, it was found that there were many white lines like eggs forming in boiling water protruding from the fish's mouth, and there were a lot of them, and there were no other abnormal manifestations.
This is a real thing, and although 30 years have passed, I still remember it vividly, and I feel that it is incredible, and I feel that I may not have the opportunity to practice this kind of practice in the future.
